For the renewable energy control, a cascade connection of the boost and the buck converter is proposed. Phase difference between converters in the first and the second stage plays a key role for determining conversion efficiency. The output resistance is discussed for evaluating efficiency.
A new configuration of a triport system is presented. In this system, when the ac line switches to the inverter under a failure of the ac line, transients do not appear in the output voltage. The battery for the inverter is charged by the phase control of the inverter. And so there is no battery charger in this system.
